Can you get parental controls for mobile safari on iPhone ?

Just wondering. Actually I feel guilty about watching porn but i keep doing it so I needa block it so I dont do it how can I. I would sell my iPod or something because Jesus said u Shuld cut out your eye if it be sinnin I think maybe figuratively and he's like saying get rid of things that make you sin. But I need my iPod touch for homework too and I have a bible app so it ain't all bad.
